What is the maximum number of recessed lumineers that can be installed on a 20 amp 277 v branch circuit? Each lumineer will draw 36.8 W at 277 V. These lumineers will be operated continuously.

Final answer:

The maximum number of recessed lumineers that can be installed on a 20 amp, 277 V branch circuit, considering the safety limit to 80% capacity, is 120 lumineers.

Step-by-step explanation:

To determine the maximum number of recessed lumineers that can be installed on a 20 amp, 277 V branch circuit, we must first calculate the maximum continuous power allowed on the circuit. Safety regulations limit continuous use to 80% of the breaker's current capacity. For a 20 amp circuit, this capacity is:

20 amps × 277 volts × 0.8 (80%) = 4,432 watts

Each lumineer draws 36.8 watts at 277 volts. Therefore, the maximum number of lumineers is the total allowable power divided by the power per lumineer:

4,432 watts ÷ 36.8 watts per lumineer = 120.43

Since you cannot have a fraction of a lumineer, the maximum number of lumineers that can be installed is 120.
